Hi. I’m brand new here. Have read a few very informative posts but need some advice. I’m looking for a way to hook up a generator to well pump when power is out. I’ve attached a photo of my well pump wiring in the basement. I have an electrical shut-off switch you can see on the wall. This is a main power switch for the circuit that goes to the pump. Could I turn that switch into an outlet and put a male plug on the end of the wires that go to the pump? Then I could plug it into the outlet normally but when power is out I could unplug from the outlet and connect to an extension cord to generator? Not sure if I am missing anything here because seems relatively easy. Thanks in advance!
